I saw that article, ABQ, ands found it interesting but potentially somewhat wrong-headed. Here is a good comment someone posted:

(below is from the article)

"Statistics like this are a good reminder that, even though college
tuition is famously outpacing median incomes, there is still something
more expensive than going to school. Very often, that is not going to
school."

(now the comment)

The most expensive, of course, is going to school and not finishing. If, say, 70% of marginal college students wouldn't graduate (currently half of students don't finish their program in 5 to 6 years- http://nces.ed.gov/pubsearch/p... - and there's probably a selection effect that means the marginal students would do worse), how does that change the rate of return?"
